Tropical Weather Outlook
NWS National Hurricane Center Miami FL
700 PM EST Mon Nov 30 2020

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

A gale-force, non-tropical low pressure system centered a couple of
hundred miles north-northwest of the Madeira Islands continues to
produce a broad area of showers and thunderstorms well to the east
of the center. This low has changed little in organization over the
last 24 hours, and environmental conditions are expected to be only
marginally conducive for it to acquire subtropical characteristics
over the next day or so as it drifts southwestward. Afterwards,
conditions are forecast to become unfavorable for further
development. Regardless of subtropical development, this system will
continue to produce strong winds and locally heavy rains in the
Madeira Islands through Tuesday. Additional information on this
system can be found in High Seas Forecasts issued by Meteo France.

1. This is the last regularly scheduled Tropical Weather Outlook of
the 2020 Atlantic Hurricane Season.  However, a Special Tropical
Weather Outlook will be issued to discuss the low over the
eastern Atlantic by 1000 AM EST Tuesday, or earlier, if necessary.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...low...30 percent.

High Seas Forecasts issued by Meteo France can be found under WMO
